IPSP contributed to the EFSA pest categorisation of groups of viruses, viroids and phytoplasmas of fruit trees and small berries

Within a specific Framework Partnership Agreement (GP/EFSA/ALPHA/2017/02 – Lot 5 GA 1), IPSP experts collaborated with the European Food Safety Authority (EFSA) to perform the pest categorisation of groups of viruses, viroids and phytoplasmas infecting Cydonia, Fragaria, Malus, Prunus, Pyrus, Ribes, Rubus and Vitis. IPSP researchers collected the needed data and participated to the activities of the working groups on plant viruses categorisation and on bacterial plant pathogens established by the EFSA Scientific Panel on Plant Health. Based on extensive literature searches, viruses/viroids or phytoplasmas infecting one or more of the host genera under consideration were listed to collect evidence on their geographic distribution within and outside the European Union (EU). After a consultation with EU Member States to collect further data on the distribution of these pathogens, viruses/viroids and phytoplasmas not known to occur in the European Union (EU) or occurring only in restricted areas of the EU (non-EU pathogens) were further categorised to evaluate whether they meet the criteria assessed by EFSA to qualify as potential European Union quarantine plant pests. In the first step of this process, about 200 viruses/viroids and 27 phytoplasmas infecting fruit trees and small berries were identified. A total of 94 non-EU viruses/viroids and 10 non-EU phytoplasmas were categorised, with the results of this activity detailed in the following EFSA scientific opinions published in the EFSA Journal:
